Oh. I hadn't realised. Anyway, with the patch removed the card supports XV in X windows and with the patch installed it doesn't. If the firmware always fails to load what does it do?

The firmware doesn't always fail to load; it loads fine. Something is wrong with yourt setup. Attach your xorg log and dmesg output for both cases.
